Definitions

  • the invention relates to a filter element having at least one inner and one outer shell body, of which at least one shell body has a cross-sectional shape deviating from a circular shape and the facing contact surfaces for the system substantially all filter pleats of a pleated filter web, wherein the filter folds from the pleat height forth are subdivided into individual groups, each with a plurality of adjacent filter folds of a common fold height.
  • Filter elements of this type are commercially available. In connection with fluid systems of various kinds such filter elements are widely used for the filtration of process fluids, hydraulic fluids such as hydraulic oils, liquid fuels and lubricants, for the treatment of liquid media and the like. In many cases, in fluid systems in which the filter elements are used, only a limited space for installation or installation of the plant parts are available that contain the relevant filter cartridge-like filter elements. On the other hand, in order to be able to filter correspondingly large filter flows, a sufficient size of the filter surface provided by the filter element is required.
  • the known filter elements typically composed of several layers of different filter materials, zigzag folded or pleated filter web, which is placed around a solid, arranged in the interior of the filter element, provided with passages supporting tube.
  • the filter web also called the filter surface part, is guided in the web longitudinal direction through a cutting unit in which the filter web is tailor-made to size before it is moved on to a folding machine, in which the zigzag shape or the pleat is formed.
  • the cut filter web is then separated into web sections, which are then formed into a tubular body and thus form the filter element.
  • DE 10 2004 026 862 A1 relates to a filter element receivable for filtering fluids in a filter housing and formed in the manner of a filter cartridge extending along a longitudinal axis in the form of a body in which an internal fluid space is surrounded by filter material.
  • the body of the filter element has a cross-section in the form of a deviating from the circular uniform thickness.
  • filter elements of the same thickness are each installed in such a positional orientation in the filter housing that they are closest to the central region of their arcuate with the larger radius of curvature outside to the wall of the filter housing.
  • a filter element of the type mentioned is out DE 20 2009 000 969 U1 known.
  • the known filter element has a pleated filter medium and two end disks and an outer cross section which deviates from a circular cylindrical shape.
  • the filter medium has wrinkles with different levels of wrinkles, which vary stepwise between a first fold height and a second fold height.
  • the end DE 20 2009 000 969 U1 known flat air filter element has areas with different degrees of wrinkles, wherein the folds of the same height are juxtaposed in sections and the folds are produced from a single continuous web.
  • the invention has the object to further improve the ratio of filter surface to required installation space, so that plant parts, which are provided for the filtration of fluids concerned, can be made particularly space-saving and immediately the largest possible filter area available stands.
  • a filter element according to the invention is characterized in that filter folds of at least one further third group are arranged between two adjacent filter folds of different groups such that the filter folds associated with the third group have a common fold height which is different from the respective fold height of the filter folds of the two adjacent groups, and / or in the type of curvature different from one another wrinkle heights, which produces a transition between the fold heights of the two adjacent groups have.
  • Advantageous embodiments of the filter element according to the invention are subject matters of the subclaims.
  • the filter element according to the invention can be arranged in non-symmetrical space geometries to provide the largest possible filter area.
  • the jacket bodies are designed in accordance with an installation space. Erfindungsgedungshack If the filter folds are designed and arranged in such a way that the distance, in other words the free space, between the inner and outer jacket body is maximized, in other words the filter folds extend along the respectively available filter space between the outer and inner jacket bodies.
  • the filter pleats are arranged directly following one another and / or parallel to one another.
  • the filter space is used optimally for the formation of filter surface.
  • the filter folds are generally perpendicular to the direction of the typically rectangular filter web.
  • the rectangular filter web is closed jacket-shaped to form the filter element.
  • the filter web is preferably connected at its filter web ends to a tubular filter jacket.
  • the pleat geometry and the geometry of the filter element can be varied and selected depending on the respective installation space, the flow conditions, in particular the specific surface load, and / or the filter size.

  • the wave or sinusoidal shape is preferably formed only on the outside or the inside of the filter web or on the respective jacket body; However, it can also be provided on both sides.
  • Filter pleats with a smaller pleat height are generally more mechanically stable and lead to a stabilization or increase in the mechanical stability of the entire filter surface part.
  • Filter pleats with greater pleat height have, because of their formation a larger web area is needed, a larger filter area and thus an increased dirt holding capacity. In this way, the separation efficiency, ie, the ⁇ -values is improved.
  • the combination of filter folds with smaller and larger fold height simultaneously achieves mechanical stabilization and improved dirt holding capacity or separation efficiency.
  • the cross-sectional shape of the inner and / or the outer jacket body is given by a convex polygon, in particular a Reuleaux polygon or a uniform thickness.
  • the characteristic feature of a Reuleaux polygon is to have constant width regardless of the direction in which it is measured.
  • Such a designed filter element can be installed in an installation space with the largest possible area cross-section. The deviating from the circular shape of a Reuleaux polygon or equal thickness makes it possible to accommodate a larger filter area in a given installation space, as would be possible with a filter element circular cylindrical cross-sectional shape.
  • the deviating from the circular shape of the same thickness allows to integrate the filter element in adaptation to the given limits of installation space to save space, that in the given installation space, a larger circumference of the filter element and thus a larger filter surface is available than when installing a cylindrical Filter element would be possible at the same installation location.
  • the filter folds along the filter web follow a periodic course, preferably with a period of 15 to 20 filter folds, arranged.
  • the minimum and maximum pleat height or pleat depth is selected according to the purpose and the installation space.

  • the filter fold height of at least one first and at least one second group of filter folds is in each case of the same height, and to the extent that equal fold heights are distributed repeatedly over the circumference of the filter element.
  • a period of filter folds is always selected which is adapted to the available filter space.
  • this adaptation also applies to the number of juxtaposed wrinkles in order to avoid sharp transitions.
  • the filter pleats are uniform and / or evenly arranged.
  • homogeneous properties of the filter element can be achieved.
  • the specific surface load on the inflow side of the filter element can be made homogeneous.
  • the filter folds are formed in cross section at least partially zigzag and / or sickle-shaped.
  • the production of a zigzag-shaped filter fold is particularly easy to fold.
